derivative of

9 tan^{2} (7 x)

126 sec^{2} (7 x) tan (7 x)

Solution steps

\frac{d}{d x} (9 tan^{2} (7 x))

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 9 \frac{d}{d x} (tan^{2} (7 x))

Apply the chain rule:

2 tan (7 x) \frac{d}{d x} (tan (7 x))

= 2 tan (7 x) \frac{d}{d x} (tan (7 x))

\frac{d}{d x} (tan (7 x)) = sec^{2} (7 x) \cdot 7

= 9 \cdot 2 tan (7 x) sec^{2} (7 x) \cdot 7

Simplify

= 126 sec^{2} (7 x) tan (7 x)

\int \frac{cos ( x )}{1 + sin ^{2} ( x )} d x

x \to 4 - lim (\frac{x + 4}{2 ^{x} - 4})

\int_{3}^{6} (x - 5)^{2} d x

4 y^{^{''}} - y = 0, y (- 2) = 1, y^{^{'}} (- 2) = - 1

y^{^{''}} - y^{^{'}} - 6 y = e^{3 x}
